Money Train 4
Money Train 4 is the final release from Relax’s Money Train series, and I argue that this last installment was the best of all. In typical Money Train style, the fourth installment blends a futuristic aesthetic with the rugged Wild West theme, creating a cinematic gaming experience.
Top among Money Train 4’s many unique extras is the Money Cart feature, featuring over 20 modifiers that skyrocket the potential payout. These modifiers include Bonus Symbols that award up to 10x your initial wager as a reward and features like the Collector, Persistent Collector, Payer, Sniper, Arms Dealer, and Necromancer. The buy feature enables instant access to a standard or advanced respin round starting at 100x the cost. Even at the lowest bet, the potential win of 150,000x is worth the risk.
The Money Train 4 RTP is alright at 96.10%, but be prepared for a wild ride – Relax Gaming has created the most volatile game I’ve seen with this last installment.
Das xBoot
Nolimit City releases slot hits month after month, but Das xBoot has managed to keep its spot at casinos’ featured lists the longest. The stats are nothing to write home about, with 96.03% RTP and 22.17% hit frequency. As expected, the game has extremely high volatility which can lead to wins of up to 55,200x. Classic Nolimit.
The Das xBoot game grid is placed underwater in a WWII submarine with cartoony action figures populating the reels. Standard spins pay near zero, but things get interesting when the modifiers kick in: xNudge Wilds, xWays, and xBomb Wild Multipliers. These can stack during the free spins and provide bombastic payouts indifferently of which symbol you manage to stack in the right spot.
Laughing Buddha
Although it was released in 2022, the Laughing Buddha slot has remained a massive fan favorite, largely due to its vibrant graphics, unique gameplay mechanics and high 56,043x max win potential! This 5×3 Asian-themed slot, which is set against a backdrop of temples and cherry blossoms, combines classic ‘Book of’ slot features with the Chinese symbol of good fortune.
The intricate Asian design that welcomes you upon launching this video slot is visually appealing. However, what truly sets Laughing Buddha apart are its turbo-charged Wilds, which feature 2x or 3x multipliers and substitute for other symbols. You can also activate free spins with the Play Feature or by landing three Golden Urn scatters, which expand to cover the entire reels and boost your chances of landing a big payout.
Laughing Buddha has a high RTP of 96.64% for the base game with 28 paylines. This video slot also has a competitive jackpot race that rewards players closest to a jackpot trigger point with a share of the prize pool. Combine these with the high volatility of this Habanero slot, and you’re guaranteed intense gameplay.
Angel vs Sinner
Pragmatic’s 2024 release Angel vs Sinner is a spin-off of the popular Zeus vs Hades slot. This game has yet to outshine the original, but it still topped online casino charts this year. The max win is set at 15,000x, and the RTP is a solid 96.56%.
All game modes (standard and free spins round) are boring until the expanding wild symbols show up on the reels. These stack during the free spins and carry anywhere between 2 – 100x multipliers. Angel vs Sinner is worth playing just for having the opportunity to land three or more expanding wilds on adjacent reels.
The remake of Zeus vs Hades is sexier in my opinion too, with the two conflicting figures working side by side instead of enabling two separate game modes based on volatility. This Pragmatic Play release simply feels more complete.
Fire Stampede
Regular collaborators, Wild Streak Gaming and Pragmatic Play, once more joined forces to deliver a savannah-themed, 6×5-reel slot machine with 1,875 ways to win. This high volatility slot combines striking visuals of fiery bison and wildlife features with a max win of 4,275x your bet and a hit rate of 1 in 3.75 spins to deliver rewarding gameplay.
The Connect and Collect mechanic is Fire Stampede’s standout feature, letting you create chains of special symbols to unlock respins, free spins, and jackpots. The slot machine has Minor and Major jackpots that deliver maximum payouts of 25x and 200x respectively. But if you’re lucky enough to land a Grand Jackpot, you can win up to 4,000x your bet!
You can trigger Free Spins on Fire Stampede by landing scatter symbols. Alternatively, you can use Connect and Collect to get up to 25 spins with retriggers, while the Bonus Buy lets you purchase free spins for 100x your bet with a slightly higher RTP of 96.10%.
SixSixSix
Despite featuring a controversial satanic theme, Hacksaw Gaming’s SixSixSix video slot became an instant hit with its playful 1950s cartoon-inspired visuals and above-average RTP of 96.15%. This video slot has a white-and-black aesthetic, with whimsical devils Balthazar and Beelzebub gleefully dancing around the reels. However, the game features truly set the SixSixSix slot machine apart.
SixSixSix’s main attraction is the Wicked Wheel feature, which you can trigger by landing Blue or Red ‘6’ symbols on reels 1, 3, and 6. The Blue Wicked Wheel offers multipliers up to 10x and boosts base-game payouts up to 100x, while the Red Wicked Wheel provides multipliers as high as 20x or prizes up to 500x your bet!
Besides the Wicked Wheel, SixSixSix offers you a chance to win ‘Speak of the Devil’, ‘Let Hell Break Loose’, or ‘What the Hell’ free spins by landing ‘6’ symbols on Wicked Wheels. You can also use the upgradeable ‘Deal with the Devil’ feature to win up to 20 free spins, increasing your chances of landing the 16,666x max win on this high-volatility slot.
Cai Shen’s Palace
At first glance, Cai Shen’s Palace Asian theme might seem cliche. However, this NetGame slot machine quickly distinguishes itself with its unique Hold ‘N’ Link mechanic. You activate the Hold ‘N’ Link when six or more sphere symbols land on the reels, triggering a respin bonus where spheres lock into place.
Whenever a new sphere appears on the reels, Hold ‘N’ Link resets to three respins, offering multiple opportunities to win the game’s Mini, Minor, Major, or Grand jackpots. The best thing about Cai Shen’s Palace is that Hold ‘N’ Link isn’t just a rare treat – this feature appears more frequently during gameplay, as noted by several players.
Cai Shen’s Palace Hold ‘N’ Link slot has an average RTP of 96.1%. You can expect to land medium-sized wins with the game’s medium volatility, and the game’s 100 paylines offer a max win of 100x per line. The slot machine also offers generous free spins, where you can combine expanding wilds and mystery symbols to land impressive payouts.
Sweet Bonanza 1000
I won’t lie; Pragmatic Play slots hold a special spot in my heart. And this year, the developer outdone itself by releasing hits back-to-back. The 1000 slot series focused on their most popular games, revamped with advanced graphics, more action-packed music, and higher volatility and max win potential. The best aspect of Sweet Bonanza 1000 for me is the super buy bonus.
Sure, you can get 1000x multiplier bombs during the standard free spins round as well, but the super bonus guarantees 25x multipliers minimum for 500x the stake.
This element makes landing the highest multiplier so much easier. The max win capped at 25,000x is the icing on the cake.
3 Clover Pots
The 3 Clover Pots – Double, Mystery, and Collect – have unique boosters that make your gameplay truly rewarding. The Double Pot multiplies your payouts x2, the Mystery Pot reveals random prizes, while the Collect Pot gathers all bonus symbols and adds their values. You can activate any pot with the slot’s Magic Pots feature, which you can trigger by landing one or more special symbols on the reels.
3 Clover Pots also features a Hold & Win bonus game activated when six or more Gold Clover symbols land on the reels. This bonus round grants three respins that reset anytime a new clover appears, with your goal being to claim the Grand Jackpot of 5,000x your bet. If you can’t get Grand, 3 Clover Pots has Mini, Minor, and Major jackpots that provide 15x, 50x, and 150x rewards respectively.
Some other features you can enjoy with 3 Clover Pots include a Free Spins round that awards eight spins, with the Leprechaun Wild doubling your wins by 2x. The slot machine has a below-average RTP of 95.74% and medium volatility providing steady wins.
Cash Pig
From the name, you might be forgiven for thinking that Cash Pig is an animal-themed slot. However, this luxurious slot from Booming Games depicts living the high life in Las Vegas. Flashy icons like jet planes, luxury planes, and diamonds are set against a shimmering nightscape, perfectly displaying an air of extravagance.
That said, Cash Pig isn’t all about glamour, with the slot machine featuring several intriguing bonus features. The Free Spins round, which features Minor Elimination and Major Upgrade mechanics, is excellent. Minor symbols are removed after wins, creating cascading reels. Major symbols, on the other hand, transform into golden versions with doubled values. You can also use the Piggy Bank bonus, triggered when the Piggy Bank lands on reel 5, to collect coin symbols for higher payouts worth up to 50x.
Thoughtful additions like the ability to change where the game menu is located and smooth bet adjustments enhance Cash Pig’s gaming experience, making it easy for you to play from desktop or mobile. Although the RTP of 95.11% is slightly below average, the Cash Pig slot makes up for this with its high volatility and max win potential of 8,000x.
Bonus1 Thoughts on Popular 2024 Slots
The online casino market proves year in and year out that online slots are what gamers are after. Sure, new live dealer games and instant win titles get their moment, but 95% of casino lobbies are slot machines.
The companies that keep releasing titles that players love are Pragmatic, Hacksaw, Nolimit, and Relax Gaming. You get the occasional hit by less-known providers like NetGame, but the big 4 have found the secret sauce.
I selected the above 10 slots based on the top-performing games at online casinos throughout 2024. What is clear as day from my research is that the most popular slots are high volatility titles with OK RTPs that revolve around the bonus rounds. Base game wins are barely noticeable, while the jackpots are life-changing.
The inclusion of bonus buys makes newer slots more suitable for high rollers. Yet, online slots like the ones trending this year could see you go from a $20 deposit to $30,000 in an instant, which is why they topped casino charts in the first place.
